I am dense.

Went to everquest.h and to edit...

Did Find ServerZoneEntryStruct...

Got line reading

struct ServerZoneEntryStruct

Scrolled down to find last unknown...

Found line reading:

/*0262*/ uint8_t unknown260[7];

Is this the correct line to change? And if so, do I change the 260 to 119, or the [7]?

Thanks, and thank you for posting these changes.

[uRit1u2CBBA=]

when you see something like "unknown0290[7]" -- the varaible name is "unknown0290" -- named such since it starts at the 290th byte of the structure, and is of length 7.

So if you need to change it to length of 119, then it will look like:

unknown0290[119]

[Cyra]

Well, its not the 260. Changed those and got error during compile in everquest.h.

Not sure whether to change the *0262* or the [7] next, but sure wish I remember what those numbers were before I made the changes.

[uRit1u2CBBA=]

I just looked at my version of the code, and I had a length of 115, not a length of 7 -- so either you're example came from somewhere else, or you have a really old version of the code, which then other problems are expected to still exist that has been fixed -- you may have to wait for a new tarball.

[Cyra]

Oops...missed the above post while I was posting.

Thank you kindly.

[Cyra]

Dang, I just did a new CVS download. Is it not current?

[uRit1u2CBBA=]

No - the latest relese wasn't pushed to CVS to my knowledge -- look in the news for the .15 tarball release, and follow it's instructions for installation (then changing the 3 pieces of the everquest.h file before compiling)

[Cyra]

I went to the Help section and followed the FAQ for a fresh install. This is much better.

Really appreciate the help. Thank you.

does this make skittles work? if so i must have done something wrong because i only get map + myself and nothing else heh

[I<3EQ]

I'm a big fan of self deprecating humor so I feel compelled to post this here.

I was just editing everquest.h while grouped in an OoW zone. My linux machine shares a keyboard and mouse (but not monitor) with my windows machine via KVM. For some reason, after I edited the file, it would just not compiled. I went back and looked at the lines I had edited. I didn't accidently remove any punctuation or operators, I didn't change any variable names by accident -- I was dumbfounded.

Then, as I was casting a spell and had to duck out real quick on my EQ machine... I realized what key sequence I used... 'dd' -- the sequence for deleting a line in vi. It dawned on me that I must have accidently removed something while editing the file last time because I thought I was ducking on my windows machine but was really in vi on my linux machine.

Sure enough, open up everquest.h and missing from the first line was the opening /* for the comment block. I r newb.

I personally think its a SoE conspiracy to stop us from using show. :p

[don'tdoit]

working great here, skittles and all.

[KaL]

Worked for me. Ah, beautiful skittles. Taste the rainbow.

[cjd1]

Use the tarball, not cvs. Make clean (if you've built in this dir before), and make again.

[Frank25]

flog me with the newbstick :P

Managed to forget to "make install"

you'd think after 4 years or so of running linux + SeQ i should knowbetter hehe

[Mortician]

Call me a newb but I am unsure which things I have to change in the everquest.h file.

Anyone show me the parts of the file to change (i.e. cut and past them into a message).

I haven't run unix in a few years and the info is appreciated.


Mortician


Note: Got it working. I just needed a little help in figuring out the c code. Thanks again. :)

[uRit1u2CBBA=]

Search for the name of the structure, scroll down to the end of the structure definition, change the length of the last "unknown" element.

If you don't know enough about C to follow those steps, wait for the next tarball.

Sorry to be so blunt, but this isn't CSCI 1001.

[Leetlewon]

Yea these instructions don't work for seq5... I checked CVS, and both the .14 and .15 tarballs. All 3 have the identical last line in ServerZoneEntryStruct which is:


/*0262*/ uint8_t unknown260[115];

[Leetlewon]

Here is the last line in the current cvs for seq4:


/*0262*/ uint8_t unknown260[7];

I'm thinking this fix is for seq4, not seq5.

[uRit1u2CBBA=]

I'm running 5, and the fix originally posted works just fine.

I think 4 is behind.

I don't think CVS has been updated in a while -- 5.?.15 was released only as a tarball, not as a CVS update.

[Leetlewon]

..... ok so then why if I download the tarball showeq-5.0.0.15.tar.bz2 and look in src/everquest.h under struct ServerZoneEntryStruct do I not see length 7 for unknown290 as indicated?

This is the entire struct (it's not there):

This is the entire struct (it's not there):


Because he's the one who said it was 7 - and he pulled it from CVS - which was out of date.


Dang, I just did a new CVS download. Is it not current?

The original poster just stated what it should be, never what it was.

[Leetlewon]

This is getting really confusing.

I see the source of confusion. The correct change is from


/*0262*/ uint8_t unknown260[115];

to


/*0262*/ uint8_t unknown260[119];

There is no unknown290...

The reason changing unknown260 to length 119 for Cyra didn't work is because he has version 4.

[Cryonic]

other than these minor changes SEQ 5.x is up to date in CVS, but the tarball is recommended over it as it reduces the requirements on the user to just the standard tarball install commands.

[Nurseling]

OK i'm getting no maps after makeing the initial change i can manually load them fine any ideas. This is the text i pulled from the terminal screen.

charProfileStruct from 11416 to 11526 was awhile ago and there were a handful of realignments in that struct to support OoW, one of which causes maps to not get loaded. Get the latest tar, apply the changes in the first post in this thread, ./configure && make && make install. Your seq wasn't working before yesterday's live patch anyways!

Oddly it worked flawlessy. LEt me giv it a shot though.

[Nurseling]

Well Started over with a new directory and a fresh unzip of the tar ball showeq-5.0.0.15.tar.bz2
And it works now not sure what i did wrong. but thank you for makeing me go back and do the quadruple check thing.

[bwonderve]

no wonder it wasnt working... I edited the wrong unknown in serverzoneentry....


Duh :D

[tfadonis]

How were the changes indentified in everquest.h? I am trying to figure out how to use the OpCode decoder and am having a hard time finding a good source of information to help me understand it all. I have searched around but any more direction would be useful and appreciated. Thanks in advance.

[st00pidn00bie]

Thanks piggy.. Works great.

[Noobian]

I'm running 5.0.0.14 and the changes worked just fine on it the SECOND time I compiled.

The first time I compiled I typed:
# make -f Makefile.dist && ./configure && make && make install

the second time I compiled I typed:
make distclean
make clean
make -f Makefile.dist && ./configure && make && make install


works like a charm!

Since I have a Celeron 375 running ShowEQ it takes a while to compile, I put all the commands on one line and just walk away.

These were struct changes. It was nothing more than seeing size mismatch errors on the console and changing the unknown padding placeholder at the end of the structs so that they corresponded correctly to the new packet stream.

Thanks CodePig - worked perfectly for me right off the bat!

[Vprecision]

Thank you CodePig and everyone else who helped clarify how to make this update work. It only took me a few minutes to figure this out and install the updated version. Keep up the good work!
